  As shown in FIG. 1, the heat exchange type ventilator of the present invention is housed and attached to the back side of the ceiling surface, has an opening 1A on the lower surface, and has a rectangular shape in cross section, and heat exchange. A large number of the exhaust flow paths 22 and the supply flow paths 21 are alternately stacked in the depth direction of the box 1 so that the exhaust flow paths 22 and the supply flow paths 21 cross each other through a plate, and heat is generated between the supply air flow and the exhaust flow. The heat exchange element 2 that is exchanged to reduce energy loss due to ventilation, and the air supply fan formed by the supply air blower motor 5a and the air supply casing 5b so as to communicate with the supply air inflow surface 2d of the heat exchange element 2 A blower 5 and an exhaust blower 6 formed of an exhaust blower motor 6a and an exhaust blower casing 6b are provided so that the exhaust suction port 24 faces the exhaust flow outflow surface 2a of the heat exchange element 2.

  The heat exchange element 2 is arranged between the partition 1a and the partition 1b integrated with the box 1, and the one side 1c inside the side surface of the box 1 is placed indoors at one vertex 1d which is a corner of the heat exchange element 2. It is divided into an air supply channel outlet 3 side and an indoor exhaust channel inlet 4 side. The laminated surface of the heat exchange element 2 is formed in a rhombus or a square.

  The outdoor air supply channel inlet 7 and the outdoor exhaust flow are formed on the side surface 1e opposite to the one side 1c inside the side surface of the box 1 where the indoor air supply channel outlet 3 and the indoor exhaust channel inlet 4 are formed. The air outlet 8 is opened adjacent to the air outlet 8, and the air supply inlet 23 of the air supply fan 5 is connected to the outdoor air supply passage inlet 7 through an air supply filter 9, which will be described later. An exhaust fan 6 is connected to the exhaust passage outlet 8 so as to communicate therewith. A cylindrical portion 7b, a partition 8b formed in the cylindrical portion 7b, an air supply inlet 7a which is a duct connection port for supplying air, An exhaust outlet 8A, which is a duct connection port for exhaust, is provided, and a two-layer pipe 10 is connected to the air supply inlet 7a and the exhaust outlet 8b. The two-layer tube 10 is divided into two flow paths by a partition 10a.

  Further, the apex angle formed by the supply air outflow surface 2e of the heat exchange element 2 and the side 1c inside the side surface of the box 1 is set to the apex 1d which is the corner of the heat exchange element 2, and heat exchange is similarly performed. The box 1 has apexes 1d that are the corners of the element 2 as apexes, and the apex angle formed by the exhaust flow inflow surface 2f of the heat exchange element 2 and the side 1c inside the side surface of the box 1 is substantially equal. In contrast, the heat exchange element 2 is arranged.

  Note that a blower lid 12 that forms a flow path and covers the exhaust fan 6 and the air supply fan 5 is attached to a part of the opening 1A of the box 1. That is, the blower lid 12 is formed from the heat exchange plates 1a and 1b extending from the two corners adjacent to the corner 1d of the heat exchange element 2 to the inner side surface of the box 1 in the opening 1A. It is comprised so that 1 side 1e may be covered.

Since the element 2 is disposed, the length of the four sides of the box 1 can be reduced, so that the entire ventilator can be downsized. Moreover, since the structure which brings the air supply blower 5 and the exhaust air blower 6 closer to the center with respect to the box 1 can be realized, the outdoor air supply flow path inlet 7 and the outdoor exhaust flow path outlet 8 communicating with the blower are brought close to each other. When the arrangement is made to communicate with the two-layer pipe 10, both the exhaust flow and the supply air flow can be smoothly communicated with the two-layer pipe 10, and both the exhaust performance and the supply performance can be achieved.

  Moreover, according to this Embodiment, since it was set as the structure which has arrange | positioned the exhaust blowing direction 6d of the exhaust fan 6 in the position which cross | intersects the suction direction of the air supply fan 5, a big resistance arises in formation in an airflow. Without effectively using the space inside the box 1, the size of the box 1 can be reduced. Further, when connecting the two-layer pipe 10 divided so that the inside can be divided into the exhaust flow 6e and the supply air flow 5c, it is advantageous as a ventilation device connected to the two-layer pipe without applying a large resistance or the like. An arrangement can be realized.

  Further, according to the present embodiment, the exhaust blow direction 6d of the exhaust blower 6 is changed downstream and bent so as to be parallel to the direction of the suction port of the supply blower 5.
